1. A method of making a golf club head, comprising:
providing a golf club head body having a flat metallic ball-striking face and a rough cut groove disposed therein, wherein the maximum depth distance of the rough cut groove is shorter than the overall distance of the rough cut groove; providing a die having a projection and a plurality of texturing features; and pressing the projection into the rough cut groove to displace material adjacent the groove to alter the rough cut groove into the final groove by pressing edge material of the rough cut groove into a final groove edge configuration at an interface between the ball-striking face and the groove, and pressing the texturing features into the face to form surface texturing, wherein the rough cut groove contains a longitudinal axis and the rough cut groove is radiused at toe and heel portions of the golf club head about axes of rotation that are perpendicular to the longitudinal axis and parallel to the face.
